Tenneco (NYSE: TEN) and Cormetech Inc. today announced that they have signed a joint development agreement to collaborate on designing ultra-large diameter selective catalytic reduction (SCR) catalysts for marine engine applications. The MARPOL Annex VI and EPA Tier IV regulations require an 80% reduction in NOx emissions, thus driving the need for engines to include aftertreatment strategies such as SCR. Tenneco’s SCR solution, incorporating the Cormetech catalyst, will be designed to help the marine industry comply with the new emission regulations. “Tenneco is an established leader in designing and developing diesel aftertreatment solutions, supplying commercial vehicle and engine manufacturers globally,” said Tim Jackson, Tenneco chief technology officer. “We are pleased to partner with Cormetech to develop a unique aftertreatment solution for marine engine manufacturers, leveraging our aftertreatment technology and engineering capabilities in this market.” “For more than 20 years, Cormetech has provided reliable state-of-the-art SCR catalyst for the reduction of NOx emissions. We are excited about this collaboration with Tenneco. The joint development takes advantage of the synergistic capabilities of Tenneco and Cormetech to meet the needs of customers in the marine sector,” stated Chris DiFrancesco, Vice President and Chief Technology Officer for Cormetech.
